W3Techs alternative

W3Techs tells you what the web uses. TechSpy tells you what one company runs.

W3Techs is the authority on adoption statistics across millions of sites. TechSpy points at a single domain and returns its real stack, infrastructure, and a decision-ready read.

  • Point at one domain, get its real stack — not a percentage across all sites
  • DNS, DMARC, subdomains and hidden APIs W3Techs was never built to surface
  • Every scan ends in a Verdict, Evidence and Implications, not a raw list

Free — no card, 30 scans/day.

TechSpy — the read

High

Verdict

Modern Next.js front end backed by Segment and Intercom — but SPF passes while DMARC is set to p=none, so the domain is spoofable.

Evidence: Next.js on Vercel edge, caught via JS-runtime fingerprints; Segment, Intercom and HubSpot in the marketing stack; DMARC policy p=none — monitoring only, no enforcement.

Implications: A polished growth stack with an unguarded email domain — a clear opening for a vendor pitching deliverability or security.

Head to head

We're not pretending it's all checkmarks on our side — where W3Techsgenuinely wins, it's bolded.

What only TechSpy does

The depth W3Techsdoesn't reach — turned into an action, not a data dump.

🔍

Sees through the SPA

JS-runtime fingerprints and HTTP headers read React and Next.js apps that leave HTML scrapers near-empty.

🧭

A read, not a list

Tools grouped by meaning, plus Verdict, Evidence and Implications with High/Medium/Low confidence — so you know what to do next.

🕵️

Deep Scan & Interact

Headless browsing with HAR capture surfaces hidden APIs and SDKs; Interact clicks and fills to reveal post-interaction tools.
